Listening to comments of those from all walks of life, most folks know little about finance and banking.
I place politicians at the top of my list, among this group of financially ignorant. I insist, If they knew more about finance, many would not be intellectually on the left.
So, it is entirely understandable that bashing bankers is always fashionable, especially during economic recessions. Finding scapegoats is handy. It makes up for any guilt politicians have in helping foment our economic distress.(See the Earl J. Weinreb NewsHole® comments and @BusinessNewshole at Twitter.)
